High N soil indicates total addition of 112 mg N as nutrient solution throughout the duration of the experiment; C1 or T1 denotes parental exposure to 0 or 500 mg CeO2-NPs per kg soil at 1st generation, C2 or T2 represents current or 2nd generation exposure to 0 or 500 mg CeO2-NPs per kg soil, C1C2 or T1T2 indicates parental exposure to 0 or 500 mg CeO2-NPs per kg soil at 1st and 2nd generations; C3 or T3 denotes current or 3rd generation exposure to 0 or 500 mg CeO2-NPs per kg soil. Values are means ± SE; n = 12.
*, **, ***, **** represent significance at p < 0.10, 0.05, 0.01, 0.001 respectively.
